Comment on: Frailty in elderly patients with acute heart failure increases readmission

The study by Danika et al.1 titled ‘Frailty in elderly patients with acute heart failure increases readmission’ is worth to read. The effect of frailty on readmission rates in elderly patients with acute heart failure is a significant and current issue that the authors have explored. Although the study offers insightful contributions to the field, I have found several areas that could use more elaboration and improvement to reinforce the research findings.
